I've been using New Wash for over a year and I'm really pleased with it - cleans my hair well and I don't need to use conditioner. But it's very expensive. Can anyone recommend an alternative which is SLS and silicone free? I don't mind if it doesn't lather but I don't want to start making my own hair washing stuff, leaving something on my hair for half an hour or mucking about with vinegar rinses, etc!
